Thanks! I'll check into it.
I do have one thing for sure, and that is the resistor bank impedance. It is definitely around 17. I took numerous readings and they were all around 17.1-17.2 ohms.
My switch seems correct. It is the same one that you had pictured, except DPDT. I just used one side of the switch.
I will try to check the ground connection today. I have the ground attached to my intake manifold. I also have to note that I use the same ground for my grounding kit. Would this be affecting it?
